Abstract
In accordance with an embodiment, a method of operating a base station configured to communicate with at least one user device includes transmitting a reference signal to the at least one user device, receiving channel quality information from the at least one user device, and forming a beam based on the channel quality information received from the at least one user device.
Claims20
A user equipment (UE) configured to communicate wirelessly in a wireless network, the UE comprising:
- a processor;
- and
- a non-transitory computer readable storage medium storing programming for execution by the processor, the programming including instructions to:
- receive multiple reference signals transmitted over different beam directions from a base station (BS);
- report channel state information to the BS, based on channel measurement of the multiple reference signals, wherein the channel state information comprises at least one index of at least one of the multiple reference signals, the at least one index is used to indicate at least one beam direction over which the at least one of the multiple reference signals are transmitted;
- and
- receive, from the BS, at least one data signal transmitted over the at least one beam direction indicated by the at least one index.
A method of operating a user equipment (UE) configured to communicate wirelessly in a wireless network, the method comprising:
- receiving, by the UE, multiple reference signals transmitted over different beam directions from a base station (BS);
- reporting, by the UE, channel state information to the BS, based on channel measurement of the multiple reference signals, wherein the channel state information comprises at least one index of at least one of the multiple reference signals, the at least one index is used to indicate at least one beam direction over which the at least one of the multiple reference signals are transmitted;
- and
- receiving, by the UE, at least one data signal transmitted over the at least one beam direction indicated by the at least one index from the BS.
A computer program product comprising computer executable instructions stored on a non-transitory computer-readable medium, wherein when executed by a processor, the instructions cause the processor to:
- receive multiple reference signals transmitted over different beam directions from a base station (BS);
- report channel state information to the BS, based on channel measurement of the multiple reference signals, wherein the channel state information comprises at least one index of at least one of the multiple reference signals, the at least one index is used to indicate at least one beam direction over which the at least one of the multiple reference signals are transmitted;
- and
- receive, from the BS, at least one data signal transmitted over the at least one beam direction indicated by the at least one index.
A non-transitory computer-readable medium, wherein the computer readable medium is configured to store a computer program comprising instructions, wherein when executed by a processor, the instructions cause the processor to:
- receive multiple reference signals transmitted over different beam directions from a base station (BS);
- report channel state information to the BS, based on channel measurement of the multiple reference signals, wherein the channel state information comprises at least one index of at least one of the multiple reference signals, the at least one index is used to indicate at least one beam direction over which the at least one of the multiple reference signals are transmitted;
- and
- receive, from the BS, at least one data signal transmitted over the at least one beam direction indicated by the at least one index.
